Seasonal variation of near-surface methane sources. (a) The interpretative diagram of methane is referenced from Bernard et al. (1976), Whiticar (1999). Bacterial source is the microbial produces, thermogenic source is the thermo genic generation of hydrocarbons. Data points are obtained through this experiment. (b) Samples numbers of different methane source. Nature gas hydrate (NGH) samples data cited from Dai et al., 2017.
